Johnny's home-built CPU corner (and other stuff, maybe)

8080 CPU, built entirely by DTL-technology

T-Cycle Generator

Note:  The small board on the top left is there only to provide an 8 MHz clock.  None of the IC there is part of the 8080 CPU.  Its only a 74HC393 and a 74AC04.

I'm not going to publish the DTL schematic here, only the logic overview.

Homebuilt CPUs WebRing

Join the ring?

To join the Homebuilt CPUs ring, drop Warren a line, mentioning your page's URL. He'll then add it to the list.
You will need to copy this code fragment into your page (or reference it.)
Note: The ring is chartered for projects that include a home-built CPU. It can emulate a commercial part, that′s OK.
But actually using that commercial CPU doesn′t rate. Likewise, the project must have been at least partially built: pure paper designs don′t rate either.
It can be built using any technology you like, from relays to FPGAs.
